This essay is a feminist, historical exploration of body parts in short science fiction stories by women. In early-twentieth-century stories about prostheses, blood transfusion, and radioactive experiments, Clare Winger Harris, Kathleen Ludwick, and Judith Merril use body parts to explore fears of damage to masculine identity by war, of alienation of men from women, and of racial pollution. In stories from the last quarter of the twentieth century, the South American author Angélica Gorodischer depicts a housewife's escape from oppressive domestic technology through time travel in which she murders male leaders, while Eileen Gunn offers a critique of bioengineering and sociobiology, satirizing fears of women in modern business and of erasure of identity in global corporate structures. An end-of-the-century fiction by the African American Akua Lezli Hope imagines a black woman altered through cosmetic surgery to become a tenor sax and critiques technologies that transform women's bodies into cultural signifiers of social function and class.
